How does the drug fentanyl appear on a urine drug screening test Will it come up as an opiate?

Fentanyl will definitely show up in a drug test and it will show up as an opiate because it is part of the class of drugs that are chemically similar to morphine. Fentanyl is in fact 100 times more potent a drug that morphine and is the first line of treatment in dealing with cancer for the treatment of pain. The drug has been around since the 60s and is classified as a drug that has to be sold under medical supervision because of its potential abuse. As far as drug testing goes, the substance is fat soluble and since the method delivery is mostly transdermal, the chances of it remaining in the body for a long time are very good. This means that you might have ingested the drug at one point of time but it would remain in your body being very slowly metabolized over a longer period of time.

Fentanyl is a class of drugs called opiods. These drugs work primarily on the pain pathways of the brain and work by inducing a sense of euphoria as well as dulling of pain. There are natural substances that are created in the body that work on the opiod pathways as well and these are called endorphins. These are created and released in the brain as a reward and gratification after achieving some kind of task – literally speaking, they give you the high sense of achievement. These are naturally released in the body after accomplishing a task, sexual activity, and also after extremely strenuous exercise. Fentanyl is normally administered as a transdermal patch where it is absorbed in the skin and dissolves in the fat of the body from where it is slowly released into the body over a period of 8 to 12 hours. It is because of this slow release that it is effective over a period of time. Unlike morphine, however, the drug is not very general in effect and Fentanyl tends to be more localized in its effect.

Despite an 8-12 hour release mechanism, the drug can still be detected in the body. This is especially the case when you have a lot of body fat on you. Your only chance of beating the drug test is to stay off the drug for a week and indulge in vigorous exercise or abstain from eating altogether in the daytimes so that your fat reserves are used up.
